| 摘 要： | 提出了一种优化风力机翼型气动特性的设计方法。在现有风力机翼型的基础上,通过改变其最大厚度位置至后缘部分的外形进行优化计算。采用N-S方程计算翼型的流场及气动特性,以提高风力机切向力同时减小其法向力为目的,用二维线性插值的方法进行多目标优化。以DU 93W 210翼型为例,针对风力机翼型气动性能本身的矛盾性,根据实际需求提出几种方案加以优化。结果表明,在不同的性能需求下,本文所提出的设计方法能取得较好的效果。

| Abstract: | A design method for optimizing the aerodynamic performance of wind turbine airfoils is presented.The calculation is optimized on the existing wind turbine airfoil through changing the outline of the range from the position of its maximum thickness to its trailing edge.The flow field and aerodynamic characteristic of airfoil are obtained by using the Navier-Stokes(N-S) equations,then the method of two-dimensional linear interpolation is used for multi-objective optimization,which is tried to increase the tan... |
